I was paying $2700/month 13 years ago for a higher-end family plan when I owned my own business. I'm not surprised then, if I paid $32k/year 13 years ago, that some plan today might be $85k. US health insurance is indeed crazy expensive. You will see some people paying less, but that's because large businesses subsidize costs, some of them only use the big insurance companies for administration, and pool their own funds to pay from. What individual people pay varies wildly.
Socialised healthcare is not a utopian dream and is riddled with problems. However I can’t see how costs of even a fraction of those cited here don’t motivate people to demand change. A heart bypass graft, cancer treatment or a joint replacement every year could be paid for and there would be cash left over (but not in the US obviously).
